But the time travel element of Avengers: Endgame would have, rather easily, allowed for Carrie Coon to reprise the role at a much more substanial capacity.
At least one dead character from Infinity War was supposed to return in a bigger capacity in Avengers: Endgame, but that didn’t quite work out.
Had Carrie Coon appeared in Avengers: Endgame, it certainly wouldn’t have hurt her resume, or pocketbook, as the movie overtook Avatar as the highest-grossing release in history.
As MCU fans may recall, Proxima Midnight met her demise while fighting Black Widow, Okoye and Scarlet Witch during the climax of Avengers: Infinity War.
